Researchers defy 19th-century law of physics in 21st-century boost for energy efficiency This defies 150 years of conventional wisdom concerning electricity and magnetism, and means they can now measure the thermodynamics of magnetism. Diodes are analogous to one way valves in a pipe, that only let water flow in one direction, and this one only allows a magnetic field to travel from one source to another in one direction, producing an artificial monopole. Using two diodes like this to measure both ends of a magnet simultaneously, could shed light on their particle-wave duality and why heat and magnetism are always proportional. The technology is so analog and so new, its rather pointless to even speculate what all the applications might be, because its like somebody just reinvented electronics. Along with the new atom radios and weirdness they've cooked up lately, this is the stuff of next generation Star Trek technology.
